The Museo del Traje is a cool museum showcasing 500+ years of style—from 16th-century Habsburg court gowns to Paco Rabanne’s 1960s metal dresses. The modernist building (1969) hides a secret garden café perfect for post-exhibition café.

Don’t miss:
- The "Bata de Cola" (flamenco’s most extreme train, worn by Lola Flores)
- Balenciaga’s 1940s designs (the gallery’s crown jewel)
- Free photo ops in the mirrored "Infanta Margarita" room
